a system gets too hot, an alert is sent to the system management controller. The
administrator can then turn the system off.
• Monitor EP80579 device registers
During normal run time, the system management can poll all error registers in the
device. When an error condition occurs, the event can log in the system
management event log. If the system crashes, the administrator can review the
system management error log to find out what caused the crash.
• Monitoring in the out-of-band operation
When the system is in standby or is powered down, some system management
capabilities are still available, such as power on, access to the IPMI system event
log (SEL), Field Replacement Unit log (FRU), and pre-boot/BIOS boot process.
•Power failure
The system management can monitor the powergood signals on EP80579 to detect
power subsystem failure.
•System reset
The reset button on the front panel is routed through the BMC, allowing the BMC to
monitor and control reset to possibly prevent reset from occurring. Also, the BMC
can detect system live lock using a timer for monitoring the system. This remote
management is used to reset the system.
• Monitor processor events
System management monitors the processor’s THERMTRIP#, PROCHOT#, IERR#,
and other signals and takes appropriate action when necessary. This action includes
logging the event, sending a warning to the administrator and shutting the system
down (if necessary).
• Clear CMOS
If the CMOS needs to be cleared, the administrator can clear it remotely via the
BMC.
• Emergency management port
The emergency management port (EMP) provides serial port access to the BMC,
which may be accessed while the system is powered down. It provides the user
with a command line interface (CLI) that can be used to access the SEL, FRU, and
service boot partition.
• Platform event paging
The BMC performs platform event paging (PEP) to alert system administrators of
system events and reduce server downtime. The administrator can get an alert by
pager or over a network about the system events using a UART or external serial
modem.
• System event log
The BMC supports system event log, FRU, and SDR. The BMC logs all events
detected by the hardware sensors. The system event log is synchronized with the
BIOS real-time clock to provide an accurate timestamp for logged events.
13.3 Enabled System Management Vendors (Optional)
Several system management vendors listed below can be consider for the system
management feature design. See Table 69.
